I honestly want to understand what you're saying but I'm still a bit confused. You say birds existed since before mammals, as the Bible says, but mammals are found in rock much older that the oldest rock with a fossil bird. (Science says 4x older.) If that conflicts with the Bible which should I believe?Interesting theory. Fish appear in much older rock layers than whales do. Did fish 'degenerate' into whales? If not, what did?
Yes, fish and birds existed since before mammals. You have an excellent point. You got it right with that one. There is not a single argument against that fact.
Saying that, your point agrees 100% with the bible.
Mammals are a different step in creation.Since their creation, mammals -as fish and bird did it before as well- started to decay.
I'm still unclear on the process of degeneration. Got an example?
